Yes, that's the exact right method to use.

If you are trying and having trouble, post some of your code.

My first question would be: do you have a file upload form element in the form? If so, this will not play nicely with getAttribute()

Hi,
Did you try HttpServletResponse.getQueryString() ?

getQueryString() is actually a method of HttpServletRequest.

You know what? I'm totally out to lunch. I must have had a brain freeze.

If you are submitting a form, or click on a link that contains name/value pairs, then the way to get these items is with getParameter()

So if the URL to the servlet looks like:

http://www.localhost:8080/app/servlet1?name=foo&name2=bar

then here is how you access the name and name2 parameters...


When you programatically *add* things to a request or a session, the way to get these 'extra' things is within the attribute space. setAttribute() and getAttribute() are used for this purpose. Only those things that you "set" with setAttribute can be "gotten" with getAttribute.

Sorry for that confusion!
